      How are older organic pesticides more dangerous to the environment??

      Neem oil for example is completely safe afaik.

        The newer pesticides are designed to work as effectively as possible. Due to their effectiveness, a limited amount is required to be applied to the soil. The FDA approved organic pesticides aren’t as effective. This requires additional applications and more being applied each time (vs the newer non-approved pesticides). More pesticides being applied means more runoff and possibility of contamination to streams and ground water. The soil can also be over saturated and be damaged by the increased concentration.
